Description

Technical Field

[0001] This utility model relates to the field of waterborne epoxy resin curing agent production technology, and in particular to a filter for the production of waterborne epoxy resin curing agents. Background Technology

[0002] Waterborne epoxy resin curing agents are a class of curing agents applicable to various epoxy resins and offering different curing speeds. Waterborne epoxy resin curing agents are in liquid form. During the curing agent production process, some insoluble solid impurities are generated, which need to be filtered out using a filter.

[0003] Existing filters lack self-cleaning capabilities. After prolonged use, a large number of solid impurities become trapped in the filter mesh, causing blockages that require manual disassembly and cleaning, which is quite troublesome. Therefore, in view of the above situation, there is an urgent need to develop a filter for the production of water-based epoxy resin curing agents that is convenient for filtering insoluble solid impurities in curing agents, easy to clean, and not prone to clogging, in order to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a filter for the production of water-based epoxy resin curing agents, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A filter for producing water-based epoxy resin curing agents includes an outer casing, an automatic slag removal mechanism, an automatic opening and closing mechanism, and filter screens. Two filter screens are disposed inside the outer casing, and a support shaft is fixed to the edge of each filter screen. The support shaft is rotatably connected to the outer casing. An automatic opening and closing mechanism for driving the two filter screens to rotate in opposite directions is installed on the outer casing. An automatic slag removal mechanism extending into the outer casing is installed on both the left and right sides of the outer casing. The automatic slag removal mechanism is used to clean the filter screens. The automatic slag removal mechanism includes: a first motor, an eccentric cam, a conductive plate, a guide rod, a spring, and a brush. The brush is located inside the outer casing, and a guide rod penetrating the outer casing is fixed to the brush. The guide rod is in sliding contact with the outer casing and is cuboid in shape. A conductive plate is fixed to one end of the guide rod, and a spring is disposed on the outside of the guide rod. One end of the spring is fixed to the conductive plate, and the other end is fixed to the outer casing. The first motor is fixed to the outside of the outer casing, and an eccentric cam is fixed to the output shaft of the first motor. The eccentric cam is in contact with the conductive plate.

[0007] Preferably, the automatic opening and closing mechanism includes: a second motor, a first gear, a second gear, a transmission shaft, a driving wheel, a driven wheel, and a transmission belt. The second motor is fixed to the outside of the outer casing. The first gear is fixed on the output shaft of the second motor. A second gear meshing with the first gear is provided on one side of the first gear. The second gear is fixedly installed on the transmission shaft. The driving wheel is fixed on the transmission shaft. The driving wheel is connected to the driven wheel through the transmission belt. The driven wheel is fixed on a support shaft. The output shaft of the second motor is fixed to another support shaft.

[0008] Preferably, the top of the outer casing is provided with a feed inlet.

[0009] Preferably, a drain pipe is fixed to the lower end of the outer casing and connected thereto, and a valve is installed on the drain pipe.

[0010] The beneficial effects of this utility model are as follows: In normal use, the filter for producing water-based epoxy resin curing agents has two filter screens in a horizontal position, attached to each other. Material is added through the inlet, and insoluble solid impurities are filtered out. The filtered material is discharged through the drain pipe. After a period of use, the filter screens are cleaned. First, the valve is closed, and clean water is added to the outer casing. Then, a second motor drives a support shaft and the filter screen to rotate in the same direction as the output shaft of the second motor. The second motor drives the first gear, the second gear, and the transmission shaft to rotate in the opposite direction to the output shaft of the second motor. The transmission shaft drives another support shaft and the filter screen to rotate through the driving wheel, the driven wheel, and the transmission belt, thus causing the two filter screens to rotate in opposite directions. The two filter screens are rotated to the brush position, and the brush bristles penetrate the mesh of the filter screen. Simultaneously, the first motor drives the eccentric cam to rotate, which in turn drives the transmission plate, guide rod, and brush to vibrate back and forth, thus cleaning the impurities clogged in the filter screen mesh. After cleaning, the valve is opened, and the impurities are discharged with the water flow. In summary, this invention facilitates the filtering of insoluble solid impurities in the curing agent, and the filter screen is easy to clean and not prone to clogging. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Specific implementation examples are given below.

[0022] See Figures 1 to 7In this embodiment of the present invention, a filter for the production of water-based epoxy resin curing agent includes an outer casing 1, an automatic slag removal mechanism 2, an automatic opening and closing mechanism 3, and filter screens 4. The top of the outer casing 1 is provided with a feed inlet 101 through which material is added. A drain pipe 5 connected to the lower end of the outer casing 1 is fixed thereto, and a valve 501 is installed on the drain pipe 5, through which filtered material is discharged. Two filter screens 4 are provided inside the outer casing 1, and a support shaft 401 is fixed at the edge of each filter screen 4. The support shaft 401 is rotatably connected to the outer casing 1. An automatic opening and closing mechanism 3 is installed on the outer casing 1 to drive the two filter screens 4 to rotate in opposite directions. An automatic slag removal mechanism 2 extending into the interior is installed on both the left and right sides of the outer casing 1, and the automatic slag removal mechanism 2 is used to clean the filter screens 4. The automatic slag removal mechanism 2 includes: a first motor 201, an eccentric cam 202, a conductive plate 203, a guide rod 204, a spring 205, and a brush 206. The brush 206 is located inside the outer housing 1. A guide rod 204 penetrating the outer housing 1 is fixed on the brush 206. The guide rod 204 is in sliding contact with the outer housing 1. The guide rod 204 is cuboid in shape to prevent relative rotation with the outer housing 1. A conductive plate 203 is fixed to the end of the guide rod 204. A spring 205 is provided on the outside of the guide rod 204. One end of the spring 205 is fixed to the conductive plate 203, and the other end is fixed to the outer housing 1. The first motor 201 is fixed to the outside of the outer housing 1. An eccentric cam 202 is fixed on the output shaft of the first motor 201. The eccentric cam 202 is in contact with the conductive plate 203.

[0023] The automatic opening and closing mechanism 3 includes: a second motor 301, a first gear 302, a second gear 303, a transmission shaft 304, a driving wheel 305, a driven wheel 306, and a transmission belt 307. The second motor 301 is fixed to the outside of the outer casing 1. The first gear 302 is fixed on the output shaft of the second motor 301. A second gear 303 is provided on one side of the first gear 302 to mesh with it. The second gear 303 is fixedly mounted on the transmission shaft 304. The driving wheel 305 is fixed on the transmission shaft 304. The driving wheel 305 is connected to the driven wheel 306 via the transmission belt 307. 06 is fixed on a support shaft 401. The output shaft of the second motor 301 is fixed to another support shaft 401. In use, the second motor 301 drives one support shaft 401 and the filter screen 4 to rotate. The rotation direction is the same as that of the output shaft of the second motor 301. The second motor 301 drives the first gear 302, the second gear 303, and the transmission shaft 304 to rotate. The rotation direction of the transmission shaft 304 is opposite to that of the output shaft of the second motor 301. The transmission shaft 304 drives the other support shaft 401 and the filter screen 4 to rotate through the driving wheel 305, the driven wheel 306, and the transmission belt 307, so that the two filter screens 4 rotate in opposite directions.

[0024] Working principle: In normal use, the two filter screens 4 of this water-based epoxy resin curing agent production filter are horizontal and attached to each other. Material is added through the inlet 101, and insoluble solid impurities are filtered out by the filter screens 4. The filtered material is discharged through the drain pipe 5. After a period of use, the filter screens 4 are cleaned. First, valve 501 is closed, and clean water is added to the outer casing 1. Then, the second motor 301 drives a support shaft 401 and the filter screens 4 to rotate in the same direction as the output shaft of the second motor 301. The second motor 301 drives the first gear 302, the second gear 303, and the transmission shaft 304 to rotate. The rotation direction is opposite to that of the output shaft of the second motor 301. The transmission shaft 304 drives another support shaft 401 and filter screen 4 to rotate through the driving wheel 305, driven wheel 306 and transmission belt 307, so that the two filter screens 4 rotate in opposite directions, rotating the two filter screens 4 to the brush 206. The bristles of the brush 206 pass through the mesh of the filter screen 4. At the same time, the first motor 201 drives the eccentric cam 202 to rotate. The eccentric cam 202 drives the transmission plate 203, guide rod 204 and brush 206 to vibrate back and forth, so that the brush 206 cleans the impurities blocked in the mesh of the filter screen 4. After cleaning, the valve 501 is opened and the impurities are discharged with the water flow.
